Introduction and Features
Important Notes
1. Only compatible in vehicles equipped with a data bus controlled premium sound system. To verify compatibility in Toyota,
look for a JBL logo on the radio. In Lexus, compatible applications will have a center channel or factory subwoofer.
2. The AP4-TY12 does not support retention of the Easy Speak function.
3. Toyota Safety Connect and Lexus Enform (SOS) can easily be retained. See the Tech Brief "AP4-TY12 SOS Retention" at
PAC-audio.com for detailed instructions.
4. The factory radio's speed controlled volume, DSP, and surround sound mode are not supported by the AP4 outputs.

6. Prior to testing, cycle the ignition off and back on again to properly initilize the AP4-TY12.
7. The radio's beep setting must be enabled on the factory radio in order to hear the audible tones when making selections
through the radio.
8. Initially, if the beep through the AP4-TY12 does not match the on / off selection through the radio, cycle the beep to the
opposite setting and back, then test again.
9. The radio's beep volume and minimum volume levels are set to 0 dB by default. If you are happy with this level in your

for more details.
10. The Radio's Nav / VR Voice, incoming E-mail tone, Ringtone, In-Call, Incoming SMS / MMS tone and Incoming SMS Voice
volumes can be adjusted through the radio's settings menu as they were prior to installation of the AP4-TY12.
11. The remote output is rated at 2A of current. If more current is needed, an external relay must be used.
12. Channels 5 and 6 are non-fading outputs. The output level of channels 5 and 6 can be controlled using the supplied level
control knob.
13. The level control knob must be connected in order to manually adjust the beep volume and minimum volume settings.
14. No adjustments can be made manually using the programming button when the module is connected to a PC.
15. Due to variations between various OEM radios and even between radio modes, the radio output voltage may vary slightly
from the selected 5 volt (or 4 volt when DIP switch 2 is down) output.

1. Turn the ignition on. LED 1 on the interface will turn on and the +12v remote output will turn on.
2. Set the amp gain(s) to the desired level. We recommend using an oscilliscope and test tones to set the amp gain(s). Please
refer to the MECP Advanced study guide (p. 360) if you are unfamiliar with this process.
3. Check volume, balance, fade and EQ settings.
4. If you would like to adjust the radio's beep volume or minimum volume, do so using one of the methods outlined below. If
you are happy with the default levels, no adjustments are necessary.

Installation
1. Remove factory radio.
2. Disconnect the 28-pin harness, the 10-pin harness and the 6-pin harness from the radio.
3. Connect AmpPRO harnesses to vehicle harnesses.
4. Connect AmpPRO harnesses to factory radio.
5. Set any feature DIP switches that apply to your install.
a. DIP switch 1 is used for two channel mode. In this mode, both the TOSLINK and front RCA outputs (1 and 2) become
non-fading outputs.
b. Set DIP switch 2 on (down) to lower the RCA output voltage to 4v. Leave DIP switch 2 off (up) to keep the RCA output
voltage at 5v. See troubleshooting section on page 5 for more details.
c. DIP switches 3 and 4 are not used and should remain off (up).
6. If you are using the APA-TOS1 (sold separately) refer to the instructions included with that product for its installation.
7. Connect the AmpPRO harness to the module.
8. Connect the level control knob to the module and install in an accessible location.

10. Initially, if the beep through the AP4-TY12 does not match the on / off selection through the radio, cycle the beep to the
opposite setting and back, then test again.
11. The Yellow / Black "Mute Input from Telematics" wire will be used in conjunction with the Safety Connect / Lexus Enform
(SOS) Retention. See the Tech Brief "AP4-TY12 SOS Retention" at PAC-audio.com for detailed instructions.
12. The Brown "Mute Input From Navigation" is a spare mute lead that can be used for custom applications. The audio will be
muted whenever the Brown wire is supplied a ground.

Restoring Factory Settings
You can restore the interface to factory default settings by pressing and holding the programming button on the side of the
module until the status LEDs start blinking red. Once the LEDs start blinking red, release the button.
This reset will restore the following settings to their factory defaults:
• Radio Beeps volume level
• Enable / Disable Factory Beeps
• Minimum volume level
• Enable / Disable factory EQ
• Factory EQ frequency
• Factory EQ Q factor
Troubleshooting
1. No audio - Check to see if LED 1 is illuminated. If not, cycle the ignition off and back on.
2. Hiss at high amp gain - Set feature DIP switch 2 to the on (down) position to lower the output voltage of the AP4 to 4v. If you
still hear the hiss, lower your amp gains until the hiss is gone.
3. Cannot hear beeps when pressing buttons on the radio - Go to the Beep On / Off setting in the radio's settings menu and
make sure it is set to ON. If it is, set it to OFF and back to ON and test for beeps again. Next, set the beep volume using

Retention of SOS
(Safety Connect / Lexus Enform)
Technical Bulletin
Overview:
Safety Connect (SOS) is a subscription based service provided for select Lexus / Toyota models. Verify
the vehicle is equipped with Safety Connect / Lexus Enform (there will be an SOS button in the overhead
console) and that it is an active account, and that retention of SOS is a concern prior to proceeding.
